Gradient and derivative

Graph of a curve with an upward tangent labeled positive gradient, a horizontal tangent labeled stationary point, and a downward tangent labeled negative gradient

The gradient of a straight line is constant, but the gradient of a curve changes from point to point. To find the gradient at one exact point, we draw a tangent and measure the gradient of that tangent.

Differentiation

Step-by-step lessons covering Oxford AQA IGCSE Maths Differentiation for Core and Extended tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Core: 1C and 2C; Extension: 1E and 2E) format. Since content from any part of the specification can appear on either paper, keep number and algebra fluency sharp throughout the course rather than leaving it until near the exam.
